Architectural professionals often work with diverse stakeholders, from property developers to city planners to individual homeowners. Your email signature needs to appeal to this varied audience while clearly communicating your expertise and contact information.
Include your full name, professional designation (AIA, NCARB, etc.), firm name, and role. Multiple contact methods are important since architectural projects often involve urgent decisions and site visits. Include your direct phone, office number, and mobile number. Many architects also benefit from including their office hours and availability for site visits.
